Colin Dodds - Angle Properties (Math Song)

In geometry if you want to fare well You need to know that parallel lines They never touch They're always the same distance apart It's as if they don't like each other much And there's only one thing that comes between them Yes a line that passes right through each of them It's called the transveral And it has several angle properties Just like these Vertically opposite angles are equal! Corresponding angles are equal! Alternate interior angles are equal! Co-interior angles equal 180 Now before you try some geometry problems You're gonna need some more knowledge to solve them So listen closely up to these Other helpful angle properties See, angles in a triangle or on a line Add up to 180 every time Angles around a point or in a quadrilateral are easy They always add up to 360 Vertically opposite angles are equal! Corresponding angles are equal! Alternate interior angles are equal! Co-interior angles equal 180 ----- Song and video by Colin Dodds
